' 13 Claims. (01. 4-215) This invention relates to improvements inventilating toilets. 1

The general object of this invention is to provide a novel toiletembodying novel forced draft means for conveying obnoxious odorstherefrom.

Another object of my invention is to provide a novel forced draftventilating system for toilets.

Another object is to provide a novel toilet ventilating means which isentirely automatic in 1 operation.

A further object is ,to provide a novel toilet ventilating valvemechanism operated by applying weight to the seat.

Another object of the invention is to provide a novel toilet ventilatingapparatus wherein the parts are all mounted within the-toilet bowl andwherein the parts can be economically made and installed.

An additional object of my invention is to provide novel forced draftventilating means for a toilet bowl which is free from clogging andother troubles and which will operate satisfactorily, without need forservicing or attention, over long periods of time. p

Other objects and advantages of my invention will be apparent from thefollowing description taken in connection with the accompanyingdrawings, wherein:

Fig. l is a top plan view, with parts broken away, showing a ventilatedtoilet embodying the features of my invention;

Fig. 2 is a section taken approximately on line 2--2 Fig. l;

Fig. 3 is a section taken on line 3-3 Fig. l;

Fig. 4 is a section taken on line 4-4 1;

Fig. 5 is an enlarged fragmentary top plan view with parts broken awayshowing the seat mountin Fig. 6 is an enlarged vertical section throughthe valve .mechanism with parts broken away;

Fig. 7 is an enlarged fragmentary side elevation of the valve mechanismshown in another position with-parts broken away;

Fig. 8 is an enlarged vertical section of the The toilet bowl llincludes a base l4 and walls 55 I5 defining the usual internal chamberl8 having a lower water trap II which communicates with the usual wastepipe outlet I8.

The upper end of the bowl ii is provided with the usual rim l9 having aninternal annular water chamber 20 from which water is discharged 5through a plurality of apertures 2|. The internal chamber 20communicates with the flush tank 12 through a conduit 22 and pipe 23.

Water is supplied to the flush tank by means of a conduit 24 whichincludes a valve 25, a T 10 member 26, and a suitable coupling 21 forsecuring the conduit to the flush tank l2.

The valve mechanism l3 comprises a cylindrical body portion 28 having acentral bore 29 which is open at the lower end as at 30 and internally15 threaded at the upper end as at 3| to receive a threaded closuremember 32 which includes a packing ring 33.

Approximately midway between the upper and lower end of the central bore29 an annular boss 20 34 provides a shoulder 35, the lower side of whichis bevelled outwardly as at 36. A nozzle 3! threadedly engages the bore29 as at 38 and secures a packing ring 39 against the shoulder 35. Thenozzle 31 (see Fig. 8) includes a body portion 40 25 having a centrallyarranged upright boss 4| in which a slot 42 is provided in which a screwdriver may be inserted. The nozzle 31 includes apertures 43 in the lowerend of the boss 4| which intersect an axial aperture 44 extendingdownwardly into a cylindrical chamber 45 in the body portion 40.

Directly below the nozzle 31 and shoulder 35 a plurality of apertures 46are provided in the body 28. These apertures communicate with theexterior of the valve l3 and the ends are outwardly bevelled as at 41thus providing a more evenly distributed flow of air.

The lower end of the cylindrical body portion 28 is provided withexternally threaded portions 40 48 and 49 to receive clamping nuts 50and 5| and gaskets 52 and 53. The upper end of the body portion 28 hasan enlarged head portion 54 from which opposed bosses 55 and 56 project.A shoulder 51 is arranged above the bosses 55 and 45 5B. A bevelledportion 5'! is disposed below the bosses and is engaged by a gasket 51".

A bracket 58 having a central bore 59 engages the enlarged head portion54 and is secured thereon and against the shoulder 51 by a nut 60 which50 engages threads 6| on the enlarged head portion 54.

The boss 55 includes a central bore 62 having a reduced bore 63 at theinner end which is bevelled to provide a seat against which a 55 valve64 is normally held closed by a spring 65. The spring 65 isheldcompressed by a coupling 66 threadedly secured to the boss 55 as at 61.The coupling 86 includes a central bore 68 having an enlarged outer bore69 in which a conduit I0 is secured in place by a packing nut II andpacking l2 and has its outer end connected to a valve I3 which is inturn connected to the T member 26 by a conduit 14 thereby supplyingwater to the valve I3.

The valve '64 includes a valve rod I5 having a reduced portion I6. Thevalve rod I5 extends across the bore 29 into a central bore 'I'I in theopposed boss 56 and outthrough a packing nut I8 which secures suitablepacking I9 in an enlarged bore in the outer end of the bore TI.

The valve I3 is mounted within an aperture 8| in the rear and at oneside of the toilet bowl H and is secured in position by the nuts 50 and5I and is maintained against leakage by the gaskets 52, 53 and 5I-. Alateral opening 82 is provided whereby the nuts 50 and 5| may be easilyreached. The nut 5| secures the lower end of the valve within aconduit83 which is in alignment with the aperture 8|. The conduit 83extends down within the water held in a trap 84 by a dam 85 integralwith the walls l5. The dam provides a channel 86 in front of the dam 85and an aperture 81 at the lower end cannects the channel with the wastepipe outlet l8.

The bracket 58 has an enlarged head 88 with an aperture 89 therein whichpivotally supports one end of a shaft 90. The other end of the shaft 90is supported in an aperture on a bracket 9i secured to the toilet bowlII at the rear and at one side as at 92. The outer ends of the shaft areprovided with square shanks 93 on which is mounted shackles 94 and 95secured in place by nuts 96. The opposite end of the shackles 94 and 95engage square shanks 91 on the end of a second shaft 98 which extendthrough the rear end of the seat 99 and are secured in place by nutsI00. Thesquare shanks' on the ends of the shafts are to eliminate anytendency for the seat to twist when. weight is applied. A seat cover I0!is pivotally mounted on the shaft 90 by means of brackets I02. The

shackle 95 includes a downwardly projecting cam 95' which is inalignment with the endof the valve rod '55,

The front of the seat cover i0! is provided I, with a rubber bumper I03directly over a rubber bumper I04 on the seat99. The bumper I08 engagesthe top of the toilet bowl II. A second rubber bumper I05 on the rear ofthe 'seat 99 is a shorter than the bumper I00 and only contacts thetoilet bowl II when weight is. applied to the seat. Y

When the valve i3 is securely held in place the apertures 46 in thecylindrical body 28 are in alignment with a chamber I06 whichcommunicates with the chamber I6 by means of a .conduit I06 justabove'the normal water level I06" of the bowl. A curvedboss 101 isprovided on the toilet bowl directly in front of the lower end of theconduit I06 to provide a more gradually inclined inlet for the gas toenter the conduitl06'. An air bleed hole I08 is provided below the rimI9 of the toilet bowl H to prevent flushing water being drawn .into thevalve device I3 when the toilet is flushed and the water level I06 risesand covers the entrance to chamber I06. A groove I09 is provideddirectly below the boss 56 and its component parts-to catch any waterthat may drip amasec mally open and the seat cover I0l may be raised 5in the usual manner and upon applying weight to the seat 99, the cam 95on the shackle 95' rocks about the shaft 90 and opens the valve 68allowing water to pass through into the bore 29 thence downwardly to thenozzle 3'! and into 10 the apertures 43 wherein the water coming fromboth sides at high velocity meets in head on collision which causes amaximum of turbulence breaking up the fluid into fine globules. The

' water emerges from the nozzle in the form of 15 high velocity, uniformspray which is directed longitudinally and centrally through the bore29. As the water emerges from the aperture 88 and passes the apertures46 in the body 28 a partial vacuum is produced thereby causing a rush ofair through the apertures 86 and causing obnoxious gases to be drawnfrom within the toilet bowl ll up through the chamber N6 and into thebore 29, thence down through the conduit 83, whence it bubbles upthrough the 25 water in the trap 84 and over the dam 85 and through thechannel 86 and aperture 87 in the waste outlet pipe I8. Also the sprayfrom the nozzle 31 condenses and supplies the water for the trap 84, thesurplus escaping over the dam 30 35 Having thus described my invention Iclaim:
